Transmission Line Design Considerations

489
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Area of Science:

  • Optical Communications
  • Digital Signal Processing

Background:

  • Coded modulation (CM) is crucial for optical systems, but designing low-complexity, high-rate schemes remains challenging.
  • Existing CM systems face limitations in balancing coding gain, shaping gain, and complexity for applications like data center interconnects.

Purpose of the Study:

  • To propose a novel CM scheme that jointly optimizes coding and shaping gains with low complexity.
  • To address the stringent requirements of high data rates, low latency, and low overhead in optical communication systems.

Main Methods:

  • Combining a soft-aided bit-marking decoding algorithm for staircase codes (SCCs) with geometrically-shaped constellations.
  • Utilizing bit-wise hard-decision forward error correction (FEC) and geometric shaping for enhanced performance.

Main Results:

  • Achieved up to 0.83 dB improvement at a 10^-6 bit error rate in AWGN channels compared to existing CM systems.
  • Demonstrated up to a 24% increase in transmission reach for nonlinear optical fiber systems.
  • Enabled rate adaptivity with six data rates ranging from 450 Gbit/s to 666 Gbit/s.

Conclusions:

  • The proposed CM scheme effectively boosts coding and shaping gains while maintaining low complexity.
  • This approach offers significant performance improvements and flexibility for future optical communication systems.
